The power adapter is a power supply conversion device for small portable electronic devices and electronic appliances. It is generally composed of a casing, a power transformer and a rectifier circuit. According to its output type, it can be divided into an AC output type and a DC output type; And desktop. Widely used in telephone sub-machines, game consoles, language repeaters, walkmans, laptops, cellular phones and other equipment.

The charger uses high-frequency power technology and uses advanced intelligent dynamic adjustment charging technology. Shanghai Seneng Electric Equipment Co., Ltd. introduces new technology. The power frequency machine is designed based on the traditional analog circuit principle. The internal power components of the machine (such as transformers, inductors, capacitors, etc.) are relatively large, generally in the case of large load operation. There is less noise, but the model has strong resistance to resistance in harsh grid environment conditions, and its reliability and stability are stronger than those of high-frequency machines. Application areas: electric pallet trucks, electric forklifts, electric pallet trucks, electric lift trucks, electric tour buses, electric boats, paintings, locomotives, etc.

The switching power supply adapter is a kind of power supply that uses a modern power electronic technology to control the ratio of the time when the switch is turned on and off, and maintains a stable output voltage. The switching power supply is generally composed of a pulse width modulation (PWM) control IC and a MOSFET. With the development and innovation of power electronics technology, switching power supply technology is constantly innovating. At present, switching power supplies are widely used in almost all electronic devices due to their small size, light weight and high efficiency. It is an indispensable power supply method for the rapid development of the electronic information industry.

Switching power adapter products are widely used in industrial automation control, military equipment, scientific research equipment, LED lighting, industrial control equipment, communication equipment, power equipment, instrumentation, medical equipment, semiconductor refrigeration and heating, air purifiers, electronic refrigerators, liquid crystal displays, LED lamps, communication equipment, audio-visual products, security monitoring, LED light bags, computer chassis, digital products and instruments.
